Any hominid fossil find with molar teeth can be plugged into a new equation that reveals its species’ prenatal growth rate.

Using a new equation based on today’s primates, scientists can take a few molar teeth from an extinct fossil species and reconstruct exactly how fast their offspring grew during gestation.
The 2018 Camp Fire killed 85 people and destroyed 20,000 buildings in and around Paradise, Calif.

The way human brains develop is special – but not quite as special as you’d like to think, if we consider Neanderthals as well.
Lecanemab is an antibody that attaches to beta-amyloid proteins accumulated in the brain and allows the immune system to get rid of them.

An 18-month treatment with lecanemab slows functional and cognitive loss by 27 per cent in people with mild Alzheimer’s disease. But this is only the first step towards a real cure.
Type 2 diabetes, characterised in its advanced stages by insulin resistance, is an important risk factor for Alzheimer’s disease.

Impaired insulin receptors in the blood vessels between the blood and the brain may contribute to the insulin resistance observed in Alzheimer’s disease.
Microglia (colored green) play several essential roles in maintaining brain health and function.

Microglia, immune cells disguised as brain cells, are known as the janitors of the brain. Dialing up their usual duties just enough could provide an avenue to treat neurodegenerative disease.
Brain-computer interfaces raise many ethical questions about how and whether they should be used for certain applications.

From warfare to entertainment and VR, brain-computer interface development has extended beyond prosthetics for patients with disabilities. Missing is full ethical consideration of the consequences.

Neuroscientists know that pregnant mothers’ brains change in ways that appear to help with caring for a baby. Now researchers have identified changes in new fathers’ brains, too.
Music influences our brain from an early age.

People who had COVID were 55% more likely to develop epilepsy or seizures over the next six months than people who had influenza – but the overall risk is still small.
During adolescence the brain experiences two opposing tendencies: its capacity for control is not fully developed but the reward system is very active.
Electronic devices are not, in and of themselves, a source of visual problems. Using these devices inappropriately can interfere with the natural development of the eye, as well as reading and learning skills.

The impact of using electronic devices is critical during the first years of life, both visually and on the cognitive and social development of the child.
We hope our work can help shape building planning and design. That could be classrooms that help us concentrate, or hospital waiting rooms that reduce our anxiety.
Canadian researchers are exploring unanswered questions about concussion: How to diagnose it accurately and quickly, how to predict outcomes and promote recovery, and how to prevent it altogether.
A new theory of Alzheimer’s disease reassesses the role of beta-amyloid in the brain.

Alzheimer’s may not be primarily a disease of the brain. It may be a disorder of the immune system within the brain. Beta-amyloid may not be an abnormal protein, but part of the brain’s immune system.
Axolotls are a model organism researchers use to study a variety of topics in biology.

Why your eyes move during the REM stage of sleep has puzzled scientists for years. Researchers measured mice brains to look for a possible explanation.
